Deborah N. PeikesDeborah N. Peikes
Senior Fellow

Deborah Peikes is a senior fellow at Mathematica Policy Research. She has technical and substantive expertise in studying how to improve the delivery of primary care through medical homes; the effectiveness of care coordination and disease management for people with chronic illnesses; and the health, employment, and social integration of beneficiaries with severe disabilities.

Peikes currently serves as the project director and/or principal investigator of a large initiative to improve the performance of 500 primary care practices for the Centers for Medicare & Medicaid Services (CMS); a foundational study of medical homes for the Agency for Healthcare Research and Quality; and an evaluation of care coordination for CMS. She has conducted studies of health policies and programs for the Robert Wood Johnson Foundation, the Medicare Chronic Care Practice Research Network, Aetna, United, the United Auto Workers, and the Health Resources and Services Administration.

She has also played a lead role in evaluating the effect of insurance and employment supports provided by the Social Security Administration’s (SSA) to uninsured Social Security Disability Insurance (SSDI) beneficiaries. She has been principal investigator for studies that involved (1) designing an SSA-funded project to improve the employment outcomes, health, and functioning of SSDI beneficiaries; and (2) evaluating the SSA-funded State Partnership Initiative, which tested employment supports and benefits counseling in 12 states.


Peikes was the first author of an article on the effects of care coordination on Medicare beneficiaries in the Journal of the American Medical Association (JAMA), and has written on and spoken widely about care coordination, primary care, and disability policy. The JAMA article was awarded Best Paper by both AcademyHealth and the National Institute for Health Care Management.


Peikes has taught a graduate class on program evaluation at Princeton University’s Woodrow Wilson School of Public and International Affairs. She holds an M.P.A. in economic policy and a Ph.D. in public policy from Princeton University, and she was a Fulbright Scholar.
